Anatomy:
Untreated severe tricuspid regurgitation is associated with high morbidity and poor quality of life. Transcatheter edge-to-edge repair, which requires a detailed understanding of the tricuspid valve anatomy via echocardiography, improves tricuspid regurgitation and quality of life; however, the valve leaflets and their spatial relationships can be challenging to understand, especially for residents or colleagues unfamiliar with the anatomy.
Pathology:
Untreated severe or more TR.
Imaging Correlation:
A hand model was developed to aid in teaching and simulating valve leaflet positions for better comprehension.
Treatment:
The spatial relationships between valves and the positions of their respective leaflets referred to as the sonographer's view were accurately represented, facilitating easier understanding in the tricuspid transcatheter edge-to-edge repair era.

01:16Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
